Well from what you described if you can see the monitor with pages showing normally right from startup to a certain point I would say the monitor is probably OK = Alright. Since you see a cursor it means that the Windows system is trying to load and is stopping at a certain point which is just after the drivers for the mouse are loaded.

I think Windows has taken a dump somewhere and probasbly needs some work. A couple of questions.

I - Does your windows have Service Pack 2 installed and was it installed separately or a part of the Windows Installation?

2 - Do you have a Windows Installation disk or a Recovery disk?

When you say it turns "Dark," Do you mean the picture itself darkens, or the screen turns black? Try booting to the "F8" screen while booting up, and see if choosing the "Enable VGA mode" option gives you the same results.

To reach this screen, tap the F8 key a few times right as your Bios is about to start loading windows after all of the start up beeps and whitsles are done.

I'm wondering if maybe your video card is set to a higher resolution than your monitor can handle, or if maybe you need to reinstall your video drivers. You can most likely also try just booting into Safe mode as well via the same "F8" screen.

I apologize if this confuses you, as I realize you are a novice pc user. unfortunately I have an appointment to attend and I don't know how soon I'll be back, so hopefully somebody else on this forum will help further troubleshoot this problem with you.

Regards

Len

Try changing the resolution from Safe Mode. It won't change much there, but maybe when you restart it will be back to normal. While you're in Safe Mode, check your hardware device drivers by holding the Windows key and tapping the Pause key. Depending on how it is set up, you may have to also hit the function key as some laptops require that to enable the Pause key, so it would be function (fn) + Windows key + Pause. That should bring up the System Properties box, and you click on the Hardware tab and the Device Manager button and find your video entry to see if there are any big yellow exclamation points or question marks obvious. If there's a problem you may have to reinstall your video drivers.

check your video drivers, and do a monitor self test and check the test on the monitor.. also hook that monitor to another computer and check and see if does the same thing on another computer if so then its a bad monitor .. and vise versa
What It Do!!

This is most likely the resolution of your monitor, but could also be several other things.

In the screen where it opens, but is very small, right click on the Desktop and select "Properties"

On the "Settings" tab - set the screen resolution to 800x600 (using the little slider thingie) and set your Color Quality as low as it will go (you can adjust these upward later on).

Then click on the Advanced button

In the window that pops up, make sure that Display is set to Normal Size (96 dpi) on the General Tab.

Next, click on the Adapter Tab, and then on the "List all modes" button - ensure that it lists the mode as 800x600, High Color, 60 Hertz - then click on OK

Next, click on the Monitor Tab and ensure that the Refresh Rate is set at 60 Hertz (Hz)

Finally, click on "OK" for all the dialogs until the window closes - reboot and see if the changes have taken effect.

If this doesn't work, we can start in on replacing your video drivers - but will need to know what kind of video card that you have.

I think the right way to troubleshoot this issue to start AT THE SITE OF THE PROBLEM and work back.

In other words, if your monitor is not looking right, then replace it with a spare and see if the problem persists. If it does not, then you have isolated the problem - bad monitor, or perhaps the cable was chewed by your dog or something (don't laugh, I have seen it!)

On the other hand if you use a different monitor and the problem persists, then perhaps you have issues with the drivers. Or maybe your video card, or in the event of integrated video - the motherboard. But from what you have said, it seems like a monitor or driver issue.

hi, i think its a driver problem, because if i change my screen resolution to 800 by 600 and on medium quality the monitor goes back to its normal state.

however, i am a novice. so i could be wrong.

if it is the driver, how can i know which driver cd to reinstall?
would i have to reinstall the video card cd again?


thanks

If you give us the exact model numbers of your monitor and your computer we might be able to steer you to the download site so you can download the right drivers.

Hello, I think there is something that was possibly missed. Here is a quote from an earlier post.

ummm i'm not so good with computers, but i have a cd with new windows xp pro on it? should i try to reinstall it?

The member says, Reinstall it. I have a question did the member try to upgrade from another operating system? If so what was the operating system he had? If so this might be a problem from upgrading to Windows XP Pro.

Next question the Windows XP Pro disk is it an upgrade disk or an original equipment manufacturer disk (OEM)?

We can find out by asking the member to type in what the cd has on the front of it.

I think the driver did not get upgraded correctly and the member might have to get a new driver but only after we find out what is truly happening with the OS.

LCD screens have a native resolution. You need to know what yours is because they don't always work well at all on other resolutions.
